This tracks very closely to Evora HP numbers.
Evora S, 257 KW or 345 HP
Evora 400, 299 KW or 400 HP
Evora GT, 310 KW or 416 HP
Evora GT430, 321 KW or 430 HP
Could be that we have the following:
Emira (base)
Emira FE
Emira S
Emira R
It would make sense that to save cost Lotus would continue to carry the powertrain options over and focus on weight savings, suspension and cosmetics. I would be happy to see higher HP versions at higher price points. Would support FE prices. I would be really surprised if they brought a base version out at lower HP. However, it might support the strategy to go for volume.
